Plot IQ signals from Airspy HF+ (11)
Now coding the GUI part of the program.
Plot IQ signals from Airspy HF+ (10)
Left button drag will shift the center frequency, and Right button drag will expand or shrink the bandwidth shown.
Plot IQ signals from Airspy HF+ (9)
Dual watch, or as many watch as you wish.
Plot IQ signals from Airspy HF+ (8)
Now, trying to demodulate a CW signal.
The LO frequency is a little bit too low.
This time a little bit too high.
Plot IQ signals from Airspy HF+ (7)
The center frequency is 7074kHz.
The center frequency is now 740kHz. You can see four AM stations.
Plot IQ signals from Airspy HF+ (6)
This is in psuedo-color.
Plot IQ signals from Airspy HF+ (5)
Draw a waterfall image for IQ signals.
Plot IQ signals from Airspy HF+ (4)
Airspy HF+ Technical specifications:
- HF coverage between 9 kHz .. 31 MHz
- VHF coverage between 60 .. 260 MHz
- Up to 660 kHz alias and image free output for 768 ksps IQ
Within the receiving band of 660kHz width, you can simultaneously tune in to as many signals as you wish.
Plot IQ signals from Airspy HF+ (3)
Listening to the AM band with Gqrx and airspyhf_rx.
